This is a set of the FX AUDIO digital amplifier FX1002J+ and an AC adapter (model number LSE0110A20100-01). Both were working without any problems until recently. Although it is a used item, both the amplifier and the adapter are in good condition with no noticeable scratches or dents. There are no outer boxes or manuals, and everything in the photos is included. When shipping, I will pack it with air-cushioning material and recycled cardboard. Also, please note that it may take 2-3 days to ship. If you agree to this, please purchase the item.
